The vast majority of the work to improve railway lines, which impacts on the frequency and journey times info on the journey guides is completed over one Sat/Sun period.
So if you can't find a usual route or train departure online, it can be worth having a look at the links to the national construction work, which you will find below.
You may then have to translate what you'll find, but it can worth the effort to discover what's occurring and to glean whether you'll need to take a bus for part of the journey, or whether trains are instead being diverted.
Alterations to the usual service are often not particularly obvious when looking up the journey on a ticket booking service.
The information included below is a guide to the the more extensive construction projects which are impacting on train services for a week or more.
Therefore these are the projects which are good to be aware of if you're planning a rail pass itinerary and want to avoid any hassle, or are wondering why a typical connection isn't available on multiple dates.
These are the upcoming rail construction projects which;
1: At Paris Gare de l'Est
Works taken place solely over weekends aren't usually included on this article, but this is major, because on multiple upcoming weekends TGVs won't be able to use Paris Gare de l'Est station, so they will be using Paris Nord instead.
The dates are;
1: TGVs from/to Paris Montparnasse
The lines used by the TGV trains on the 'Atlantique' routes between Paris and Bordeaux, Rennes and Toulouse are being disrupted at different construction sites during the first 6 months of 2023.
1: In the Berlin area
On multiple dates in January to March the calling patterns and arrival /departure times of the many of the long-distance trains which serve Berlin are being altered.
Though the majority of the works are being carried out at weekends.
The key impact of the works is that some trains won't be making their usual calls at Berlin-Gesundbrunnen and Berlin-Spandau stations due to diversions.
The diversions will enable these trains to still call at Berlin Hbf, but many departure and arrival times at that station will be later than usual.
2: Cologne <> Bonn
Works on the signaling systems is impacting on the route between Koln Hbf and Bonn Hbf/Bonn-Bad Godesberg during multiple periods of time in the first quarter of 2023.
The key impact of this work will that many of the long-distance trains which would normally call at Bonn Hbf will be diverted and won't be serving the city.
The work is being undertaken during these dates:
3: Cologne <> Koblenz from Friday, January 6, 4:00 pm to Friday, February 10, 10:00 pm
Station improvement work in the Remagen area is leading to the ICE, IC and EC trains which travel between Koln/Cologne and Koblenz being diverted during these dates.
Several of these trains will be calling at Kolm Messe/Deutz instead of at Koln hbf and will be calling at Bonn-Beuel station instead of at Bonn Hbf.
This diversion will add around 15 minutes to the journey times, so these trains will be departing from stations north of Koln/Cologne 15 mins earlier than their usual timings.
4: In the Frankfurt (Main) area
From Friday, January 6th at, 22:35 pm to February 2nd at 04:35 am
from Monday, February 13th to Friday, March 17th, all day long
During these times work is being undertaken on the railway between Frankfurt Airport and Frankfurt (Main) hbf, the main city centre station and as a result the routing of many of the ICE services which typically travel this way are being altered.
Though some services will only be impacted between January 9th - 30th.
During this period:
5: Between Erfurt and Nürnberg, from January 10th to Friday, February 10th
Some ICE trains are canceled between Erfurt Hbf and Munich Hbf.
6: Between Munich and Ingolstadt from from Saturday, February 4th to Thursday, February 9th, all day long
Some ICE trains do not stop in Ingolstadt Hbf and other trains will be diverted on the longer route via Augsburg, so that they call there instead.
The trains which are diverted via Augsburg will arrive in Munich Hbf up to 30 minutes later or depart in Munich Hbf up to 30 minutes earlier.
7: The high speed line between between Kassel and Fulda
From April 1st until December 9th, a key section of the primary north<>south high-speed line in Germany is closed due to renewal works.
During the this time, the ICE trains travelling between Kassel and Fulda will be diverted on to the older classic line, which the high-speed route avoids.
The diverted and therefore slower services are the ICE trains on these routes:
However, in order to minimize disruption to arrival and departures at the extremities of the ICE routes, particularly in Switzerland, the long-standing routes of some ICE services are to be drastically altered from April 1st to December 9th.
1. ICE route 12 is the Berlin - Wolfsburg - Braunschweig - Kassel - Frankfurt (Main) ↔ Mannheim - Karlsruhe, Freiburg - Basel - Olten Bern - Interlaken route.
However, from April 1st the trains on this route will be turned around in Frankfurt (Main); and the trains will be taking an alternative route between Kassel and Frankfurt
Bern and Interlaken will be primarily served by ICE trains taking a Hamburg - Hannover - Kassel - Frankfurt (Main) ↔ Mannheim - Karlsruhe, Freiburg - Basel - Bern - Interlaken route.
So the current 1 x train per day on the Hamburg ↔ Interlaken route becomes a three trains per day service, with other departures being turned around in Basel.
2. ICE route 20 is the Hamburg - Hannover - Kassel - Frankfurt (Main) ↔ Mannheim - Karlsruhe, Freiburg - Basel - Zurich - Chur route, but from April 1st it will be having its Swiss destinations switched so that it takes over the Germany ↔ Olten - Bern - Interlaken service of route 12, instead of its calls in Zurich, Landquart and Chur.
It will also be around 45 mins slower on the part of the route between Hannover and Frankfurt (Main)
3. The Germany ↔ Zurich - Landquart - Chur service usually provided by route 20 is being covered by a major change to route 11.
Route 11 usually takes a Berlin - Leipzig - Erfurt - Frankfurt (Main) ↔ Mannheim - Stuttgart - Ulm - Augsburg - München route.
However, from April 1st it will be taking a Berlin - Leipzig - Erfurt - Frankfurt (Main) ↔ Mannheim - Karlsruhe, Freiburg - Basel - Zurich route.
As a result the Germany ↔ Zurich route will be covered by trains which won't be on a route impacted by the works on the high-speed line.
It also seems as though ICE trains won't be serving Landquart and Chur between April 1st and December 9th.
4 The usual Frankfurt (Main) ↔ München section of route 11 is to be covered by a change to route 22.
Instead of being a Hamburg - Hannover - Kassel - Frankfurt (Main) - Frankfurt Flughafen - ↔ Mannheim - Stuttgart route, it is already a
Hamburg - Hannover - Kassel - Frankfurt (Main) ↔ Mannheim - Stuttgart - Ulm - Augsburg - München route.
5. So that a direct service can be maintained between Berlin and Stuttgart, route 15 is to be extended beyond Frankfurt (Main) to provide a Berlin - Erfurt - Frankfurt (Main) - Frankfurt Flughafen ↔ Mannheim - Stuttgart route.
6. So that Kassel can maintain its hourly connection with Frankfurt (Main) hbf, despite that change to route 12, the route 13 service of Berlin - Kassel - Frankfurt (Sud) - Frankfurt Flughafen becomes a Berlin - Kassel - Frankfurt (Main) hbf route.
**8: Between Karlsruhe and Base ffrom Tuesday, April 11th to Saturday, April 15th, all day long
Some ICE trains are canceled between Karlsruhe Hbf/Offenburg/Freiburg (Breisgau) Hbf and Basel Bad Bf/Basel SBB.

(1) Until July the railway is closed between Ourense and Monforte de Lemos in Galicia.
Buses are replacing trains over sections of the following long-distance routes:
1: Work is being undertaken between Lausanne and Vevey on multiple Saturdays, which is impacting on trains which take the Geneve - Lausanne - Vevey - Montreux -Martigny - Sion - Visp - Brig route.

Hence the work, which is being carried over these weekends;
3: From February 27th to October 29th, reconstruction work is closing part of the route north of Buchs, which is used by trains on the Zurich main station - Zurich Airport - St Gallen - St Margrethen - Buchs - Landquart - Chur route, so buses will be substituting for the trains between Alstatten station and Buchs.
